According to another embodiment, the keyboard of the present invention includes a bottom plate and a plurality of keys. The plurality of keys are arranged on the bottom plate, and at least one of the plurality of keys includes a keycap structure, a lifting mechanism, and an elastic member. The lifting mechanism is detachably connected to the keycap structure and the bottom plate, so that the keycap structure moves up and down relative to the bottom plate. The elastic member is connected to the keycap structure, so that when the keycap structure is separated from the lifting mechanism, the keycap structure is detached from the lifting mechanism together.

In summary, because the present invention directly fixes the elastic member to the keycap structure, the steps of positioning and connecting the spring and the keycap to the lifting mechanism of the button are omitted. Therefore, it is only necessary to fix the elastic After the keycap structure of the component is assembled to the lifting mechanism, the user can complete the key assembly process, thereby effectively solving the problem of time-consuming and laborious assembly and positioning of the keycap and the elastic part mentioned in the prior art, thereby greatly improving the quality of the key. Convenience of disassembly and assembly.

The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings.

Please refer to Figure 1, Figure 2, and Figure 3. Figure 1 is a partial exploded view of the key 10 according to an embodiment of the present invention, and Figure 2 is the keycap structure 14, spring 18 of Figure 1 And an exploded schematic view of the buckle ring 20.

The button 10 can be preferably applied to a generally composed of an upper cover and a lower shell. The portable electronic device of the opening and closing mechanism (such as a laptop keyboard or a foldable keyboard device) can be pressed by the user to perform the input function desired by the user, but is not limited to this. As shown in FIGS. 1, 2, and 3, the button 10 includes a bottom plate 12, a keycap structure 14, a lifting mechanism 16, a spring 18, and a buckle ring 20. The lifting mechanism 16 is detachably connected to the bottom plate 12 and the keycap structure 14, whereby the keycap structure 14 can move up and down relative to the bottom plate 12 via the lifting mechanism 16.

In terms of the design of the connection between the keycap structure 14 and the spring 18 and the buckle ring 20, it can be seen from Figures 2 and 3 that the keycap structure 14 has at least one fixed hook 22 (one is shown in Figure 2, But not limited to this), the spring 18 is hooked to the fixed hook 22 and abuts against the bottom plate 12 to drive the keycap structure 14 to move away from the bottom plate 12, and the buckle ring 20 is detachably fastened to The hook 22 is fixed to clamp the spring 18 together with the keycap structure 14. In this embodiment, the keycap structure 14 may include a keycap engaging member 24, a keycap body member 26, and a spring fixing seat 28. The lifting mechanism 16 may preferably adopt a scissor foot support mechanism commonly used on keyboard keys. Design (but not limited to this, it can also adopt other common key lifting support designs, such as magnetic key design, etc.) to be detachably connected to the key cap joint 24. For example, as shown in Figure 3, the key The cap engaging member 24 may have a sliding groove 30 and a card groove 32. The lifting mechanism 16 may include a first support member 34 and a second support member 36. The first support member 34 and the second support member 36 are pivotally connected to each other. 34 has a sliding part 38 and is rotatably connected to the bottom plate 12, the sliding part 38 is slidably connected in the sliding groove 30, the second support 36 has a pivot part 40 and is slidably connected to the bottom plate 12, the pivot part 40 It is rotatably connected to the slot 32, whereby the sliding of the first support member 34 relative to the keycap engaging member 24 and the rotation relative to the bottom plate 12 and the rotation of the second support member 36 relative to the keycap engaging member 24 and Relative to the sliding of the bottom plate 12, the keycap engaging member 24 can move up and down relative to the bottom plate 12.

In practical applications, in order to improve the convenience of disassembly and assembly, the keycap engaging member 24 may preferably adopt a magnetic design to detachably engage under the keycap main member 26. In this embodiment, it can be seen from Figure 2 , The keycap engaging member 24 may have a first magnetic member 42, and the keycap main member 26 has a second magnetic member 44 at a position corresponding to the first magnetic member 42, whereby the first magnetic member 42 can magnetically attract the second magnetic member 44 to enable the keycap engaging member 24 to be detachably engaged under the keycap main member 26. Furthermore, at least one side edge S of the keycap engaging member 24 may be formed with at least one first positioning structure 46 (preferably a protruding slope structure design, but not limited to this), for example, as shown in the second As shown in the figure, a first positioning structure 46 can be formed on the side edges S on the left and right sides of the keycap engaging member 24, and two first positioning structures 46 can be formed on the side edges S located behind the keycap engaging member 24. The structure 46 (but not limited to this), and the position of the keycap body 26 corresponding to the first positioning structure 46 can be formed with a corresponding second positioning structure 48 (preferably a rib design, but not subject to this (Limited), whereby the first positioning structure 46 can be engaged with the second positioning structure 48 so that the keycap joint member 24 can be more firmly joined under the keycap body member 26. It should be noted that, as shown in Figure 2, in this embodiment, the side of the keycap body 26 of the keycap structure 14 corresponding to the second magnetic member 44 may preferably be formed with a recessed structure 27 for the user to The keycap structure 14 can be pulled through the recessed structure 27 to perform subsequent disassembly and assembly operations of the keycap structure 14.

In addition, as can be seen from Figures 2 and 3, in this embodiment, the keycap engaging member 24 corresponding to the position of the spring 18 can be formed with a through hole 50, and the spring fixing seat 28 can be formed with a fixing hook 22 And is connected to the keycap body 26 corresponding to the position of the through hole 50 (for example, the spring fixing seat 28 can use the adhesive layer 52 shown in Figure 2 to be attached to the keycap body 26, but it is not limited to this, it is also Other common connection designs can be used, such as structural engagement design, etc.). In this way, the buckle ring 20 is detachably buckled to the fixing hook 22 to clamp the spring 18 together with the spring fixing seat 28 (such as the first 3). It should be noted that, as shown in Figure 2, at least one limit stop 54 (three are shown in Figure 2, but not limited by this) can be formed on the spring fixing seat 28, and the limit stop 54 The system can abut the spring 18 laterally and be arranged in a circular arrangement with the fixing hook 22, so that the spring 18 can be positioned to the spring fixing seat 28 more accurately.

Through the above design, after the assembly of the keycap body 26 connected with the spring 18 and the keycap joint 24 connected to the lifting mechanism 16 is completed (as shown in Figure 3), the button 10 can be pressed by the user In the process of the cap structure 14, the linear deformation characteristic of the spring 18 is used to provide a linear pressing feel without a sense of passage. As for the switch trigger design for the button 10 (for example, the optical trigger design that uses an optical sensor to detect the length of the pressing stroke of the keycap structure 14 or the structure of the trigger switch that presses down the circuit board by the lifting mechanism 16 is designed to resist contact, etc.) The related description of, which is common in the prior art, will not be repeated here.

In this way, because the present invention uses the buckle ring to directly fix the spring to the keycap structure, the step of sequentially connecting the spring and the keycap to the lifting mechanism of the key is omitted. Therefore, it is only necessary to fix the spring After the keycap structure is assembled to the lifting mechanism, the user can complete the key assembly process, which effectively solves the problem of time-consuming and laborious assembly and positioning of the keycap and the elastic part mentioned in the prior art, thereby greatly improving the disassembly of the keys Convenience of installation.

It is worth mentioning that the keycap structure provided by the present invention is not limited to the three-piece detachable design mentioned in the above-mentioned embodiment. For example, in another embodiment, the keycap joint and the spring are fixed. The seat system can be directly formed on the main body of the keycap in an integrated manner to jointly form a single keycap structure, thereby simplifying the design of the keycap structure of the present invention. As for other variant embodiments (for example, only the spring fixing seat is integrated with The related description of the molding method (formed on the design of the keycap body part) can be deduced by referring to the above-mentioned embodiment, and will not be repeated here.

In addition, the button 10 of the present invention can further provide the function of changing the pressing feel. For example, please refer to Figure 3, Figure 4, and Figure 5. Figure 4 is a paragraph-sensitive elastic body 56 A perspective view of the replacement keycap structure 58 connected to the replacement keycap structure 58. FIG. 5 is a cross-sectional view of the paragraph-sensitive elastic body 56 and the replacement keycap structure 58 connected to the lifting mechanism 16 in FIG. 4. As shown in Figs. 4 and 5, the button 10 may further include a paragraph-sensitive elastic body 56 and a replacement keycap structure 58. One end of the paragraph-sensitive elastic body 56 is connected to the replacement keycap structure 58 (for example, glued Way, but not limited by this). Through the above design, when the user wants to switch the button 10 to provide a sense of passage, the user only needs to use an adjusting jig or a pliers hand tool to move the spring 18 along with the keycap structure 14 from the lifting mechanism 16 is removed, and then the replacement keycap structure 58 connected with the paragraph-sensitive elastic body 56 is assembled on the lifting mechanism 16 (as shown in Figure 5), so that the button 10 can be pressed by the user when the replacement key In the process of the cap structure 58, the paragraph-like elastic body 56 is used to provide a paragraph-like pressing feel. It should be noted that the above-mentioned keycap body part and keycap joint part keycap disassembly related design or single keycap structure design can be applied to the replacement keycap structure 58, and the related description can refer to The above description is analogous and will not be repeated here. As to which design is adopted, it depends on the actual application requirements of the button 10.
